Be it known that I, THEoDoRE M. SMITH, a citizen of the United States, residing at Bronx, in the county of Bronx and State of New York, have invented new and useful Improvements in Educational Devices, of which the following is a specification.

This invention relates to educational devices and more particularly to a device for teaching code systems andthe like.

The principal object of the inventio-n is the provision of a device whereby a person unfamiliar with the code system may very easily and quickly learn the same.

Another object of Vthe invention is the provision of a device which comprises a stationary member having letters of the alphabet thereon and a movable member having code symbols and registering marks thereon, said marks in juxtaposition with relation to the code symbols, the registering marks adapted to be brought into registration with the letters of the alphabet on the stationary member.

A further object of the invention is the provision o-f a device which is simple of co-nstruction, cheap to manufacture and highly eiiicient for the purpose intended.

With these and other obj ects in view which will appear as the nature of the in-v vention is better understood, `the same consists in the detailed construction, comb-ination and arrangement o-f parts, the essential features o-f which will be hereinafter more fully described, pointed out in the claims and shown in the accompanying drawing, in which Figure 1, is a face view of the device. f

Figure 2, is a topp-lan view of the same, i

and

Figure 3, is a vertical sectional view on the line 3-3 of Figure 1.

Referring more particularly to the drawings, the reference character indicates a base orV stationary member which may be made of any material and shape but in the present instance, is shown assquare in co-nfiguration. The base 10 is slit longitudinally and stamped therefrom are str1ps 11, said strips projecting out from the face of the base 10 upon opposite sides thereof. The said strips 11, are spaced equidistant from `the center and have suitable` indicia 1Q,

thereon in the nature of lletters of the alphabet. In the drawings, only certain vletters of the alphabethave been shown but it will said base and said strip.

be understood that-half of ,the letters may `be arranged on the strip on one' side and half on the strip of the other side. Movable i members in they nature of disks 13 are mounted for rotation as at 14, upon oppo- @site sides of the base, said disks 13 being interposed between the base 10 and the strips 11. The disks 13 have code symbols 15 rradially arranged thereon' and registering marks 16 in juxtaposition with the said symbols, the said registering marks adapted'to register with the letters arranged onthe strips 11. Anparrow is shown at 17 which is adapt? ed to register with the code symbols when the registering marks 16', are brought into registration with the different letters ofthe al habet. y 4 or example, the letter (C) is represent-y ed by the'code symbols yand it is desired to learn the code symbolof the letter Y (C), the disk 13 is revolved about its axis until the registering mark 16 is brought intov registration with the letter (C) on the strip 11 as shown in Figure 1 of the drawings. It will be understood that both sides of the device are substantially alike, merely differing in the indicia thereon and the operation is l the' same in both instances.

VVhereinY there has been .shownand described, a device showing indiciaof the al'- phabet and their respective code symbols,

it is to be understood that other suitable in- -dicia may be substituted therefor and that no limitation is made to the indicia shown in the drawings but that changes, alterations and modifications as come within the'claims may be resorted to when so desired.

What I claim as new vis:- 1. A new article of manufacture compris# 1 ing a base, strips stamped out from said base, and'disks mounted for rotation on said base, said i disks being interposed f between 2. A new article vof manufacture comprising a base, strips stamped out fro-m said base onopposite sides thereof and disks mounted for rotation on said base, said disks being interposed between said b-ase and said strip.

3. A new. article ofvmanufacture comprisbase, said strips being spaced yequi-distantl ving a base, strips stamped outfrom said from the center of said base on opposite sides thereof, and disks mounted for yrotation on said base, said disksbeing interposedy between said base and saidstrip. v

4. An educational device comprising a base, strips stamped out from said base, suitable indicating indicia arranged on said strips, disks mounted for rotation on said base, said disks being interposed between said base and said strips indicating indici a on the disks significant tol the indicating indicia on the strips, and reglstering marks in juxta- In testimon slgnature.

y whereof I have aixed my THEODORE M. SMITH.
